Abstract
A bending-resistant powder coating comprises the following components by weight: 34.29% of polyester resin, 3.02% of epoxy resin, 2.01% of dicyandiamide, 1.71% of a pigment, 29.35% of titanium dioxide, 24.52% of ultrafine barium, 1.20% of a leveling agent, 0.80% of modified starch, 0.10% of graphene, 1.2% of titanium dioxide, 0.8% of zeolite powder, 0.5% of wax and 0.5% of glass powder. The coating has simple ingredients and reasonable ratio; and the added graphene microchip enhances the electrostatic spraying performance. Compared with the conventional powder coating, the coating has the outstanding advantages of good resistance to bending. If a conventional powder coating is sprayed on a metal sheet workpiece and then stamped at 90-180 DEG C, the powder coating film cracks at the thickness of 60 mum on the workpiece; however, if the bending-resistant powder coating disclosed by the invention is sprayed on the sheet metal workpiece and stamped at 90-180 DEG C, the powder coating does not crack on the work piece when the film thickness reaches 80 mum.
Description
Technical field
The present invention relates to coating process technical field, be specifically related to a kind of bend-resistance powder coating.
Background technology
Electrostatic spraying utilizes high pressure static electricity corona field principle.Metal guide flow cup on lance head connects high pressure negative electricity, is formed positive pole by painting workpiece grounding.Stronger electrostatic field is formed between spray gun and workpiece.When powder coating is delivered to the diversion cup of spray gun from powder barrel through duff pipe by carrier gases (pressurized air), intensive electric charge is produced around it, negative charge on powder belt, under electrostatic force and compressed-air actuated effect, powder is adsorbed on workpiece uniformly, through heating, powder melts solidification (or plasticizing) uniformly, continuous, smooth, smooth film.
Powder coating is widely used in the application on all kinds of casing, workpiece and all kinds of antitheft door surface, the application on the casing be made up of sheet metal especially for all kinds of, workpiece and all kinds of antitheft door surface.The existing powder coating for spraying is not bend-resistance powder coating, and it is only for no longer carrying out the application on the casing of punching press or bending, workpiece and all kinds of antitheft door surface after spraying.In use, existing powder coating also exists when the casing be made up of sheet metal, workpiece are when after need spraying, punching press is spent for 90 degree-180 again, the weak point that powder coating film will ftracture when thickness of workpiece reaches 60um.
Summary of the invention
It is comparatively simple that technical problem to be solved by this invention is to provide a kind of composition, the bend-resistance powder coating that spraying effect is good.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of bend-resistance powder coating, be made up of the component of following mass percent:
By powder coating formulation by proportioning raw material → abundant pre-mixing in mixing tank → by forcing machine jointly extrude → compressing tablet → pulverize → grind → sieve → packaging final prod.
Described Graphene selects graphene microchip, described graphene microchip is with the long brilliant generation of the cellular fashion of solid, four valence electrons of each carbon atom formed covalent linkage in bond live, the stream of electrons of displacement can not be formed, so just can not conduct electricity, after generating, Graphene crystal utilizes the nano-milled mode of wet type, grinds with single direction, generation thickness is nanometer, and area is micronized graphene microchip.
The invention has the beneficial effects as follows: present component is comparatively simple, reasonable ratio increases graphene microchip, promotes electrostatic spraying performance; Compared with existing powder coating, there is the outstanding advantages that bend-resistance is effective, existing powder paint on sheet metal workpiece after again punching press 90 ° ~ 180 ° time, the thickness of powder coating film on workpiece will ftracture when reaching 60um, and a kind of bend-resistance powder coating of the present invention is when to be sprayed on after on sheet metal workpiece punching press 90 ° ~ 180 ° again, also can not ftracture when the thickness of powder coating film on workpiece reaches 80um.
Embodiment
The technique means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with specific embodiment, setting forth the present invention further.
Embodiment 1
A kind of bend-resistance powder coating, be made up of the component of following mass percent:
